RAIL CONSTRUCTION.

SPECIFICATION formingpart of Letters Patent No. 787,434, dated April 18, 1905.

Application filed July 22, 1904. Serial No. 217,715.

To all whom it may concern: 7

' Be it known that I, RICHARD M. BURKE, a citizen of the United States, residing at Utica,

neida county, State of New York, have invented certain new and useful Improvements in Rail Construction, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates roan improved rail construction; and [declare that the following is a full, clear, concise, and exact description thereof sufiicient to enable one skilled in the art to make and use the same, reference being had to the accompanying drawings. in which like letters and numerals refer to like parts throughout.

Acharacteristic of my invention is the employment of a wide rail-base,whichbecause of the distribution of the weight thereon lessens the wear on 'the ties or the substructureof the rail-bed and which by the employment of a removable rail-tread permits ready replacing of that part which is most sub- A further advantage is that the base of the rail is provided with grooves to engage the rim of the wheel in caseof derailment, and thus lessens the risk of disaster.'

-A further feature is that the base and the tread are so constructed that the latter might extend over the former, so as to break joint,

the two being pierced for connecting means at -regular and coincident intervals.

In the drawings, Figure l is a perspective View, and Fig. 2 is asectional view, of my device.

, Referring to the figures more in' detail. A represents railr0ad-ties 0r any other suitable substructure to support the rail portions.

B represents a rail-base which is provided between its edges with a vertical flange or web (J. projecting vertically above the base. This.

flange is formed with substantiallyparallel sides, although it is not essential that this should be so, it beingpermissible that the outer face should vary somewhat from the,

true parallel to the inner face. The base Bis grooved out adjacent to one of the faces, here shown as-the inner one, and rises from such groove 6 into ashoulder I). On the opposite eral movement.

downwardly and laterally to an edge suitable ties or substructure, as, shown by the spikes (Z in this instance.

for attachment to the I form a rail-tread with a horizontal member E and 'a vertical member E. p The under edge of the horizontal member has a grooveor cut-out a, in which the upper edge of the,

ridge or flange C may fit, enabling the mem- .ber E to rest upon such edge and to be held thereby from any perceptible degree of lat- The downward edge of the web E is formed with an edge a to rest in groove 6, supportingthe rail-tread thereon and holding the same substantially from lat eral movement. The web is'also'providedwith a shoulder e", which rests upon a corresponding shoulder b in thebaseportion. At regular intervals the ridge or flange C is pierced to receive bolts F, and the web E is likewise pierced at the same regular intervals, so that the latter may be extended over the base in'forminga railroad-bed, and on straight work the parts may be assembled without the necessity of providing other holes for the bolts F. The bolt-holes may be elongated as is necessary to provide .for any necessary yielding of theparts.

In. Fig. 1 it is shown that the ridge 0 of the base B may be extended beyond the horizontal member of the base, so as to further provide for the breaking of joints and the' rigid connection of the rail structure; It 'will be understood that the base-ridge C is suitably pierced in such extended portions to register with the holes in theweb E of the railtread. ThegroovesD are'located such adistance from the rail-tread that in case of derailment the flange of the wheel will fall into the groove and travel therein without striking the ties and doing any great amount of injury to the rail structure. Thegrooves are employed on each side of the rail to provide for derailment on either side.

Having described my invention, what I derailment, and a rail-tread having aweb to engage the base, the said base and web being pierced for bolts to permit the overlapping of'the tread with respect to the base, substantially as shown.

3. In a rail construction, a laterally-extended base portion provided with a verticallycxtehded web portion, the latter extending beyond the horizontal portion, in combination with a rail-tread adapted'to break joint with the horizontal portion of the base and with.

the vertical portion of the base, substantially as described.

'4. In arail construction, a base extending laterally from the tread-supporting member and provided parallel therewith with a groove on each side thereof to receive the flange of the wheel upon derailment, and a tread member groovedto receive the tread-supporting member of the base and provided with a web to provided in the said base toreceive the web of the tread membensubstantially as shown.

5. A rail construction comprising a base with a horizontally-extended portion,thelatter being provided with a groove to engage the wheel-flangein case of derailment substantially parallel to the rail-tread, substantially ,as shown.

6. A railway construction comprising a ridged base with a horizontally-extended pora groove adjacent thereto to receive the flange of the wheel in the case of derailment, sub- I stantially as shown.

with. a horizontally-extended portion being provided on each side of the center ridge with a groove parallel with the rail-tread to receive the flange of the wheel in case of derailment, substantially as shown.

In testimony whereof I aflix my signature in presence of two witnesses.
